To all, whom it may concern.-

Be it known that 1, PAUL Scnwrnnwsm, tinker, a subject of the Kingof Prussia, German Emperor, residing at 9 Falkensteinstrasse, in the city of Berlin, Kingdom of,

Prussia, and German Empire, have invented a certain new and useful Hair-Drying Apparatus, of which the following is a specification.

This inventionhas reference to. a hair-dry ing apparatus in which hot air is caused to flow, y means of a small fan-wheel, against the moist hair, which is dried in this manner.

The invention consists in the fact that the hair-drying apparatus is so arranged and constructed that it may be held with one hand while it is operated at the same time by the hand holding the apparatus, so that the person holding the apparatus is free to comb the hair with the other hand and is also able to direct the hot-air current toward the hair that has been combed through. An additional important improvement as compared with the hair-drying apparatuses nowin use is presented by the fact that thegear-Wheels for actuating the fan-wheel are not exposed to the action of the heatingfiame,-so that the gearing remains in working order during the life ofthe apparatus. Besides, the new hairdrying apparatus is constructed in such a manner as to yield a vigorous current of air without requiring much work.

Upon the accompanying drawings I have shown the new apparatus, by way of example, in two forms of construction.

' Figures 1 and 2 illustrate the new hair-drying apparatus in side view and vertical section and in rear view, respectively, the part serving for the reception of the heating device serving at the same time as a handle in this modification. Figs. 3 and 4 show the actuating device in two working positions. Figs. 5 and 6 are representations of another form of construction of the apparatus where a separate handle is provided for holding the apparatus, Fig. 5 showing this form of apparatus in vertical section, and Fig. 6 in horizontal section through the casing inclosing the fan-wheel.

The hair-drying apparatus comprises a cone-shaped casing a, which is connected by a curved'extension to the box-shaped casing b, inclosing the fan-wheel c and open at the front, so thatthe air-current produced by the fan-wheel is forced out at the apparatus. The cone-sha ed ing a constitutes the hand e o, the apparatus and ,is rovided at its lower elid withperforations, iioles, or the like, so that? the air may enter therein, while it is closed at the bottom by a swinging cover m, upon which the spiritlamp Zis mounted. I The shaft 11 of the fan-wheelc is j ournaled at one end in the web 1 and at the other end in a shoulder 0 of the casing a, the end of the side of the shaft projecting from the casing a being provided with a gear-wheel p, which transmits the rotating movement produced by the clockwork r to the fan-wheel a. workis actuated by" an operating-lever g, which is placedso near the conical part of the This clock.-

casing a, constituting tlie "handle, that it is possible to o erate said lever with onefinger of the hand olding the jagppara tus, while, the backward movement'lof the lever is. caused by the action of a spring; For this purpose the clockwork is provided with a ratchetwheel f, With'WhiQhzthQ ratchet-pawl i, which is pivoted to thelever g, is made to engage, the pawl beingv influenced by: the spring 7c.

When the lever g is forced hackward in. the direction of the arrow shownfin the drawings by thethumb of the hand holding the casing a, the ratchet-Wheel f is moved to a certain extent, since the ratchet-pawl '1', engages with the teeth of the said ratchet-wheel f. By

means of the intermediate wheel constituting I f the clockwork this rotation is transmitted to the shaft (1 of the fan-wheel 0, so that when the lever is moved, formstance, from-the position shown in full lines into the position.

shown in dotted lines the wheel is'making a" full revolution. As soon as the thumb is then withdrawn the spring k, which has been charged by the previous movement of the lever, (see Fig. 4, dotted position,) pulls the lever g back into the position shown in fuil lines in Fig. 3, the ratchet-pawl sliding ino eratively past the teeth of the wheel f int e well-known manner, the said pawl after hav-' ing assumed its position of rest reengaging the Wheel f, so that the next movement of the lever g by means of the thumb causes a rotation of the ratchet-wheel f, and consequently, also, of the fan-wheeld. The air expelled by the rotatiorf of the fan-wheel is replaced by the admission of fresh air entering through the holes which surround the spiritfact is liable tointerfere with the ating thefan-wheel is arranged horizontally above the flame of the small spirit-lamp and being protected from t e direct action of the heat by a screen or protecting-wall. In this modification the'lower part of the casing a is cylindrically shaped, and it is connected, by

means of a hinge or the like, with the closingcap constituting the foot mof the apparatus,

so that the spirit-lamp may be exposed by inclining the apparatus for the purpose of igniting or of refilling the lamp The cylindrical part a of the casing serves fommounting the box-shaped casingb of the fan-wheel; but it is separated from said box by a circular-shaped protecting-plate t in such a manher that the gases of combustion of the spirit and the aspirated air are deflected sidewise and are admitted to the fan-Wheel i: at the outer extremities of its vanes only. The box I) in the constructional modification herein describedis closed at the top by a cover a, which is provided with vent-holes, and which is separated from the interior of the box I) by a likewise perforated partition, upon which is mounted or attached the clockwork operating and rotating the/shaft d of the fanwheel. Thehandle s isarranged sidewise of the box I) in this construction, and above the said handle the leyer g is arranged, which projects through a suitable opening of the box-coverand which serves for the actuation of'a ratchet-wheel constructedin the manner already described or {in any similar manner. In this modification the fan wheel does not only aspirate the air of combustion, but it also aspirates fresh air at the same time through the cover of the box I), the air being expelled through the nozzle 6, arranged sidewise of thebox. By this means the effect is produced that the fan-wheel is protected against excessive heating by the flame in its centerpart also, so that the shaft of the fanwheel is also protected, the said parts being, furthermore, kept cool by the fresh and consequently cool air which is constantly in troduced from abovegs'o that they are kept in constant working, order. On the other hand, by means of the air being admitted by ed of excessive heatingof the air which is to be admitted to the hair, which would cause headache withsensitive persons.

In order to produce as vigorous and as of airexpelled from the fan-wheel, a partition or guide wall curved in the direction of the rotation of the fan-wheel is arranged in the nozzle 3), as shown in Fig. 6 of the drawmgs. 7

What I claim, and desire to secure by Letters Patent of the United States, is

1., A hair-drying apparatus comprising a fan-wheel, a casing therefor means for rotat ing said wheel, a burner connected with the fan-casing, a handle for the apparatus and a controlling-lever for the operating means located adjacent saidhandle so that said lever may be operated by, the same hand which holds the handle.

2. A hair-drying apparatus comprising a casing having its lower part of conical form and the upper portion thereof having a PAUL SCHWIDEWSKI.
